Checking and Adjusting Track Tension
1. Position the machine on a level surface. On
machines equipped with rubber tracks, position the
excavator so the tracks are positioned with mark
(1, Figure 4-22) on the top span of the track in
between drive pinion (2) and track tension roller
(3).

2. Use the bucket and dozer blade to lift the unit up
until a track is just clear of the ground as shown in
Figure 4-23.
3. Shut off the engine. Remove the ignition key and
take it with you. Lock out the controls by raising
left control console.
4. Measure the clearance of the raised track at the sec-
ond track roller from the drive gear. Deflection
should be between 3/4-1” (20-25 mm).
5. Using a grease gun, pump grease into the fitting
until the track is properly tensioned (Figure 4-23).
Note: A grease gun is supplied with machine tool kit.
6. Start the engine. Lower the unit to the ground.
7. Repeat this procedure for the other track.

IMPORTANT
Do not over-tension the track. If the track is
too tight, loosen the grease fitting to relieve
the pressure.

under pressure and cause injury. Keep your
face and body away from the fitting when
loosening.
